convert iso date to milliseconds in javascript
(10 answers)
Closed 7 years ago.
I have a date as a String like : 2015-12 for december 2015.
I would like to convert this date to get this date in milliseconds in javascript. (From the first day of the month)
How can i do it ?
Try using the Date object (new Date()).
You could do :
YourDate + "-01"
And then try to convert to a date
d = new Date(YourDate)
And finaly :
d.getMilliseconds()

Let's say I have a string 2021-08-13 and want to convert this to August 13, 2021. How would you achieve this as it's not a date object.
In my mind I can think of setting each numeric month to a text version of that month and re-arrange, however seeing if there are better ways of doing this.
Simple: convert the string into a Date object and use the toLocaleString function.
If you want to get rid of the timezone so the date stays the same wherever the user is you can first convert it into an ISO string, get rid of the 'Z' in the end, and then convert it back into the Date object.
const dateString = '2021-08-13'
const localeOptions = {dateStyle: 'long'}
const dateTimezone = new Date(dateString).toLocaleString('en-US', localeOptions)
const dateWithoutTimezone = new Date(new Date(dateString).toISOString().slice(0,-1)).toLocaleString('en-US', localeOptions)
console.log(dateTimezone)
console.log(dateWithoutTimezone)
Convert your string date to a JS Date Object
let strDate = "2021-08-13";
let date = new Date(strDate);
console.log(date.toDateString())

You can pass number of miliseconds to Date constructor like:

How can I format date from DD.MM.YY format to any other format (preferably DD/MM/YYYY) with full 4 digits year value that I can input to new Date() by using javascript?
I find similar issue but in PHP code, is there an library that can convert that in javascript?
I'm getting Invalid Date error when inputting that date format to new Date()
Vanilla JavaScript can be used to convert the date string into a Date object by calling split(",") on the string, parseInt() on each returned array item, and then adding 1900 or 2000 to the year component based on your own needs. Date() takes the year, month, and day as arguments.
Once you have a JavaScript date object, a method like this using padStart() can output the date into the DD/MM/YYYY format.

JavaScript - get the first day of the week from current date
(20 answers)
Closed 4 years ago.
$gte: ISODate("2010-04-29T00:00:00.000Z"),$lt: ISODate("2010-05-01T00:00:00.000Z")
You may get the day of the week by calling .getDay() on the date object. Once you have the day of the week, rest are arithmetic operations.
To convert Date to ISODateFormat you can use toISOString
var dateForCalculation = new Date();
var prevSunday = new Date(dateForCalculation.setDate(dateForCalculation.getDate()-dateForCalculation.getDay())).toISOString();
var nextSunday = new Date(dateForCalculation.setDate(dateForCalculation.getDate()+7)).toISOString();
console.log(prevSunday);
console.log(nextSunday);

getDate(); // 0-31, 1-based day of month,
